Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs. It serves as a building block in the production of selective serotonin reuptake inhibitors (SSRIs) and other psychotropic agents. Its structural properties make it valuable in medicinal chemistry for enhancing metabolic stability and bioavailability in drug candidates. Also employed in the preparation of kinase inhibitors and antimicrobial compounds. Widely utilized in research and development within the pharmaceutical industry for structure-activity relationship (SAR) studies.
